[0036] The implementation principle of this embodiment is: The semi-trailer bucket, which is suitable for different road conditions, is provided with gooseneck left and right beams 2. When using the device, the staff connects the bucket to the front of the vehicle through the gooseneck left and right beams 2 and the gooseneck lifting mechanism 3. This process is a prior art. When it is necessary to adjust the height of the working surface 1, the staff starts the supporting oil top 16 and the gooseneck lifting oil top 37, so that the supporting oil top 16 can be shortened, and the working surface 1 can be driven to move upward, and the working surface can be driven to move, so that the rotating block 12 can be rotated. Since the rotating block 12 and the fixed block 14 is rotatably connected, so that the rotating block 12 can be rotated, so that the distance between the rotating block 12 and the fixed block 14 can be increased, so that the number of splints 13 can be adjusted. When the number of splints 13 is increased, the height of the working surface 1 can be increased, and when the number of splints 13 is reduced, the height of the working surface 1 will be reduced, so that the height of the working surface 1 can be adjusted, so that the equipment can be adapted to different road conditions, and when pulling over-high cargo through the bridge hole, the height of the working surface 1 can be lowered to allow vehicles to pass, thereby expanding the scope of use of the equipment.

[0037] When the height of the working surface 1 is adjusted, the fixed block 14 can also rotate, and the rotation of the fixed block 14 can drive the rear beam 7 to rotate. Since a swivel support 9 is provided at the bottom, a swivel support lower connecting plate 29 is provided at the bottom of the swivel support 9, and the swivel support lower connecting plate 29 is fixedly connected to the rotating frame 26, and since the rotating frame 26 is rotatably connected to the rear bridge 25, the rotating frame 26 can be rotated, and the rear beam 7 can be rotated, so that the side of the rear beam 7 close to the fixed block 14 can be raised and lowered, and since the rotating frame 26 is rotatably connected to the rear bridge 25, the rear bridge 25 can be kept horizontal, so that the wheel 24 can be evenly stressed, thereby extending the service life of the equipment.

[0038] When steering is required, the staff pulls out the positioning pin 27. Pulling out the positioning pin 27 can make the slewing support 9 rotate, and then the slewing support lower connecting plate 29 can be rotated. Subsequently, the staff extends and contracts the steering cylinder 19. One of the two steering cylinders 19 extends and the other contracts. Since the steering cylinder 19 is rotatably connected to the steering oil top base 18 and the fixed frame 20, the fixed frame 20 can be rotated. The rotation of the fixed frame 20 can drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 can drive the steering swing arm 22 to rotate. Since the steering swing arm 22 can move inside the swing arm support scale 23, the rotating rod can be rotated, and the rotation of the slewing support lower connecting plate 29 can drive the rotating frame 26 to rotate. The rotation of the rotating frame 26 can drive the rear bridge 25 to rotate, and then drive the wheel 24 to rotate, so that the rear wheel 24 has a steering function, thereby reducing the turning radius of the semi-trailer, thereby improving the safety of the equipment.

[0039] Compared with the prior art, the present invention has the following beneficial effects: 1. The semi-trailer bucket suitable for different road conditions is provided with an adjustment mechanism 6, which can make the working surface 1 rise and fall by supporting the oil top 16 and cooperating with the gooseneck lifting mechanism 3, thereby making the rotating block 12 rotate, thereby increasing the distance between the rotating block 12 and the fixed block 14, thereby adjusting the number of the clamping plates 13, thereby making the working surface 1 rise and fall, thereby expanding the use range of the equipment; 2. The semi-trailer bucket suitable for different road conditions is provided with a positioning pin 27. By pulling out the positioning pin 27, the steering mechanism 8 can be released from the limit, so that the steering mechanism 8 can be rotated. By rotating the steering cylinder 19 and the rotating rod 21, the rear beam 7 can be rotated, and the wheel 24 can be rotated, so that the rear wheel can have a steering function, thereby improving the cornering passability of the equipment and improving the safety of the equipment.

[0040] 3. The semi-trailer bucket suitable for different road conditions is provided with a traveling mechanism 10, which can be rotated by a rotating frame 26 to keep the force on the rear wheels 24 balanced, thereby protecting the equipment and extending the service life of the equipment.
